Is it common for a population to remain in genetic equilibrium?

1) No mutations
2) No natural selection
3) No individuals in or out of a population.
4) Large population
5) Random mating
It is, however, impossible for a population to achieve genetic equilibrium. There are always going to be mutations occurring from time to time.

What is the differernce between family genetics and population genetics?
Population genetics deals with the genetics of large groups of individuals and the statistics/probability/inheritance patterns in those groups. On the whole this field of study does not manipulate genetic material and is not directly involved in breeding studies. One of the primary tenents of population genetics is that an allele will remain in a population at the same frequency as long as it is neither selected for or against. (The Hardy-Wienburg Principle).
When Hary Weinberg Law in population Genetics is not applicable if the conditions are not followed then why you study it mean what its importance?
The Hardy-Weinberg principle posits that in the absence of outside evolutionary forces, a population's alleles and genotype frequencies will remain constant. Biologists use this principle as the standard against which to test outside evolutionary forces on a population.
How does genetic information pass unchanged from one generation to the next even when a specific trait is not exhibited?
This is a principle of population genetics based on the Hardy-Weinberg Principle. A trait that is neither selected for nor against will remain in the population at the same frequency. In most populations the frequency values can be back calculated from the percentage of the population that is homozygous recessive. The basic equations are p+q=1 and p (squared) + 2pq + q (squared)=1 The value of q (squared) is the frequency of homozygous recessive individuals in the population. So if 20% of the population is homozygous recessive, then q (squared) is .20. This makes q=.45 (approx.) So, in order to produce a population where 20% of all individuals are homozygous recessive a full 45% of all the alleles at that gene locus are recessive. p=.55 p+q=.55+.45=1.0 Now all the numbers for the homozygous dominant and heterozygotes can be calculated. The approximate percent of the population that is homozygous dominant is 30% with 50% of the population represented by heterozygotes. .3+.5+.2=1 As the gene frequency for an allele decreases the less likely two individuals that are heterozygous for the trait will be to breed and produce either a homozygous recessive individual or a homozygous dominant. In the case where a characteristic is dominant and has a low frequency, the trait will be seen in family lines but rarely has the opportunity to be passed beyond a small population because there is no selection for the characteristic. An example of this is 6 fingered (polydactyl) individuals, which is a dominant trait. They exist in the population but they are rarely seen.

Why does voltage remain constant in the reverse breakdown region in a zener diode?
This space is for answering "http://wiki.answers.com/Q/Why_does_voltage_remain_constant_in_the_reverse_breakdown_region_in_a_zener_diode" Why does voltage remain constant in the reverse breakdown region in a zener diode?
The situation in which allele frequencies of a population remain constant is called?
That situation is called a Hardy-Weinberg equilibrium. Not actually seen outside of the lab.
When allelic frequencies remain unchanged a population is in genetic eqilibrium this statement expresses what?
hardy-weinberg equilibrium
What does it mean for a population to be in genetic equilibrium?
It is a situation where allele frequencies remain constant.
What is the type of equilibrium that occurs when allele frequencies do not change?
Genetic equilibrium is when the allele frequencies remain constant.
What does being in Hardy-Weinberg equilibrium mean for a population?
The Hardy-Weinberg equilibrium is a principle stating that the genetic variation in a population will remain constant from one generation to the next in the absence of disturbing factors. When mating is random in a large population with no disruptive circumstances, the law predicts that both genotype and allele frequencies will remain constant because they are in equilibrium.
What are the conditions a population must meet in order to have genetic equilibrium?
1. No net mutations occur; that is, the alleles remain the same 2. Individuals neither enter nor leave the population 3. The population is large (ideally, infinitely large) 4. Individuals mate randomly 5. Selection does not occur
The allele frequencies of a population are more likely to remain unchange if?
There is no evolution. Random mating, no immigration/emigration, or, in short, Hardy-Weinberg equilibrium holds.
What is used to describe the conditions of reaction at equilibrium?
At equilibrium the concentrations of reactants and productas remain constant.
What is used to describe the conditions at reaction at equilibrium?
At equilibrium the concentrations of reactants and productas remain constant.
How do gene frequencies change when there is no relationship between genetic variation and reproductive success?
Alleles that are neither selected for or against will remain at the same frequency in a population. (This assumes that the population is also large enough to not suffer from variation due to genetic drift.)
When a systime has reached chemical equilibrium the concentrations of the reactants and products?
When a system has reached chemical equilibrium, the concentrations of the reactants and product remain constant.
What are the characteristic of a reaction that establishes equilibrium state once?
The concentration of reactants and products remain constant.
